To all whom it may concern:

Be it known that I, EDUARD Hniazoe, a su bject of His Imperial Majesty the Emperor of Austria-Hungary, residing at Erlach, Lower Austria, in the Empire of Austria-Hungary, have invented certain new and useful Improvements in Apparatus for Testing and Registering the Degree of Inequality of Yarn, &c.; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, reference being had to the accom panyingdrawings, and to letters of reference marked thereon, which form a part of this specification.

The invention in question consists of an apparatus by means of which the degree of inequality of a cordsuch as a thread, wire, or ribbon or of a similarly-formed body may be measured and indicated, this indication being preferably registered by passing said cord between a relatively fixed surface or support anda movable surface or contact member, said movable surface being utilized to effect the measurement. In this invention this latter surface may be formed by a pendulum, which is caused by the inequalities of the cord to make corresponding movements and that can be used to produce the indication or registration.

The apparatus is represented in the accompanying drawings, in which similar characters indicate corresponding'parts in all the views,

and in which- Figure 1 shows. a broken front elevation of one embodiment of the invention. Fig. 2 is a side elevation thereof. Fig. 3 is'a detail in elevation of the record produced by the apparatus.

Referring first to Figs. 1 and 2, the stationary member consists of a block a, having a smooth upper surface, while the movable member is constituted. by the lower part or bob 6 of a pendulum 0Z, suspended from an arm I) of a frame member 0 and adapted to freely oscillate about its points of suspension. Preferably, as shown, the part c is cylindrical or suitably rounded. At the upper part of the frame member 0 a micrometerscrew 6 is arranged for the. purpose of adjusting the arm]; in such manner that the part c of the pendulum d only imperceptibly touches the adjacent face of the block a, this adjustment being maintained by a set-screw 6 disposed as illustrated in Fig. 2. The cord 7, is led from a bobbin or reel over the block a, guide-rollers g g being situated at either side thereof, and is drawn toward and wound upon a drum h, which is revolved as will be presently explained. By this movement of the cord because of the stronger: or weaker parts a correspondingly stronger or weaker swing is given to the pendulum in thedi'rection of advance of the cord. The drum h is suitably supported, and the cord f passes to it through an eye in the free end of a guide 71, mounted upon a screw-spindle i and adapted to advance along and parallel with the drum h as the cord is wound thereon and as the drum is revolved. The retraction of the guide 2' is accomplished by a hand-crank i furnished on the spindle The registration of the tests of the cord f may be various and may be effected by any appropriate devices. In the example the deflections of the pendulum d are reproduced as a diagram on a strip of paper, the tested length of cord is recorded by a counter, and the deflections are recorded upon another counter, all as will now be explained.

To the pendulum (Z, as represented best in Fig. 1, is secured, by means of an arm d, a

style 05 the point of which is arranged to touch a strip of paper is, wound on a reell and running over guide-rollers Z Z at a constant speed, the strip being traversed concurrently with the rotation of the drum it. Thus the deflections imparted to the pendulum (Z by the inequalities of the cord f are reproduced and recorded upon the strip k by the style 01 and the line so obtained constitutes a diagram of theinequalities of the cord, the deflections of the style d to the right of the center of the strip 7: indicating the thicker portions and those to the left the thinner.

For indicating the length of the cord f tested a suitably-graduated dial m is emwhose movement corresponds and is synchronous with the rotation of the drum h and is such as to indicate the actual length of the cord wound thereupon.v The shaft to comprises a freely-revolving ratchet-wheel a,

furnished with a suitably-graduated dial having a stationary pointer n, which is made to 'ployed and it is provided with a pointer m,

correspond with the zero of the dial before every operation. This ratchet-wheel a is operated in one direction by a pawl n pivoted to the pendulum d when the latter is correspondingly deflected, the movement of the ratchet-wheel corresponding to the amount and length of the movement of the pendulum. Consequently the pointer 02 registers on the dial the number of unequal portions of the yarn, cord, or the like. Another pawl n is located within a casing forming the base of the apparatus and serves to prevent the return of the wheel n. Thus a proportional number, which denotes the amount of inequality of the tested cord, can be ascertained from the number indicated by the dial of the ratchet-wheel n and from the length of the tested cord shown by the dial on.

In order to obtain a record of the percentage of the inequalities for a certain unit of length of the cord, the strip 1 6 may, as indicated in Fig. 3, be marked at certain intervals with transverse lines 70, corresponding to the proportion of its advance to the tested length of the cord and with longitudinal lines for an indication of the size of the inequalities. Instead of this special strip is a device having a marker may be combined with the apparatus and adapted to divide a plain strip automatically in correspondence with the length of the cord wound upon the drum h and simultaneously with the taking of the diagram. This device may comprise a counterroller Z situated opposite to the guide-roller Z, the circumference of the former being such as to make one revolution corresponding to a certain length of the cord f, which length is then denoted on the strip in by a marker Z, provided on the periphery of the roller Z The apparatus may be actuated in various ways. According to that illustrated a handcrank 0 operates a train of gear-wheels, (indicated by dotted lines in Figs. 1 and 2,) the gear-wheels being disposed within the casing of the apparatus and actuating the drum h and the other parts operating therewith. However, whatever the mode of driving the arrangement and operation are such as to revolve the drum in, to move the guide 2', to operate the pointer m, to advance the strip 70 and the cord f. Hence the pendulum d is deflected and the desired records are obtained, as already described.

Assuming the testing completed, the guide z'is returned to its original position by the crank 6 the spindle 2" being disengaged from the gearing.

Preferably the cord f is not wound directly upon the drum ll, but upon a shell or sleeve of tin, cardboard, or the like placed thereover for each cord to be tested, whereby the tested cord can be conveniently stored for subsequent comparison with other cords.

What I claim, and desire to secure by Letters Patent of the United States, is

1. An apparatus for testing cord, comprising a support, means for moving the cord over the support, a contact member mounted for movement in the direction of advance of the cord, and means for indicating the movement of the contact member.

2. An apparatus for testing cord, comprising a support, means for moving the cord over the support, a pendulum mounted to swing in the direction of advance of the cord, and means for indicating the movement of the pendulum.

3. An apparatus for testing cord, comprising a support, means for moving the cord over the support, a contact member mounted for movement in the direction of advance oi the cord, and means for indicating, through the movements of the contact member, the total amount of inequality of the cord.

4. An apparatus for testing cord, comprising a support, means for moving the cord over the support, a pendulum mounted to swing in the direction of advance of the cord, and a style carried by the pendulum.

5. An apparatus for testing cord, comprising a support, means for moving the cord over the support, a pendulum mounted to swing in the direction of advance of the cord, and a counter mechanism with which the pendulum coacts.

In testimony that 1 claim the foregoing I have hereunto set my hand this 13th day of April, 1904.

EDUARD HERZOG.
